First of all, Eli Manning went through practice with a new helmet that had his chinstrap snaps higher up so it would be harder for them to become unfastened with a big hit. He also had some extra padding over the gash, and proceeded through practice with no problem.
Not so with Aaron Ross. His swollen heel will be in a cast for 10 days, according to Tom Coughlin, which means he's out for the rest of the preseason. Whether his limited action in the first two games was enough to get him ready for the season remains to be seen. For now, the Giants just need to worry about getting him back ASAP. But at least tests revealed that there is no ligament tear.
DT Chris Canty had an MRI on his sore groin, but Coughlin said there was "nothing of great significance." And cornerback Terrell Thomas is suffering from a sore calf.
